TR Knight's Boyfriend is Good Medicine

Mark Cornelsen comes out to support boyfriend T.R. Knight as the pair make a mad dash to their car outside UCLA’s Royce Hall in Westwood, Calif. on Friday.

The couple and T.R.‘s Grey’s Anatomy costar Katherine Heigl (pictured below) made appearances at “Good Medicine,” a musical benefit to benefit crew members who were affected by the strike. Most of the Grey’s Anatomy and Private Practice casts were in attendance.

Check out TMZ for a video of Heigl literally pushing, pulling and jerking T.R. to not sign any more autographs.
